Together with Trideus, Filaments Directory is launching a one month contest, which will call upon users to enter their print settings for a chance to win prices for Compost3D.

Recently, Trideus launched Compost3D. This filament is fully compostable in your own back yard. If you don’t need your prints anymore, or if you want something new, you can just throw them away. To compost, this filament needs 3 things. The first is the heat of the compost bin, the second is moisture. The last necessary thing are micro-organisms, which are in every compost bin.

More information about Compost3D can be found here:

Not only will the contest give participants a chance to win various prizes, but it will also mark the start of a user-driven 3D printing filament community, one that will help optimize the way that we all use our FDM 3D printing technology. The more quality settings that are uploaded possible, the more the 3D printing experience will become easier, more reliable and less time consuming. Together, all of the inputted print settings will be consolidated into big data and used to create the best profiles for every 3D printer.


From 2pm UTC, 6th of June, 2017 to 23h59 UTC, 30th of June, 2017.


  • You must create your account on in order to participate.
  • Each registered user of the website automatically has one chance to win without sharing a setting.
  • Each valid print setting equals one chance to win, which means that the more you share, the more of a chance you will have of winning one of the prizes. There are no limits per person.
  • Please use only your own images and settings. We will check. We reserve the right to exclude settings at our sole discretion.
  • One prize per person or postal address.
  • The contest is worldwide and free of charge, except customs fees if applicable.

If you don't have a 3D printer at home and you want to participate, we suggest that you contact your local fablab, techshop, makerspace or 3DHubs users to print something with them. In case of questions or problems with the website, please send me a direct message on Twitter @filamentsdir or by using the Contact Us link at the bottom of the page.
